CKAN vs OpenFocus

CKAN helps Kerbal Space Program players find, install, and manage mods through a client connected to an online registry. Users can refresh the registry and search by mod name, identifier, author, or relationships. CKAN uses mod metadata to select mods for the game version, install dependencies, and identify conflicts or incompatibilities. By default, a mod must be marked compatible with the exact game version; users can choose additional compatible versions, and an All filter can display incompatible mods. The client provides graphical, console, and command-line interfaces. It runs on Windows, macOS, and Linux, with installation options for several Linux distributions. The executable can manage game installations from any folder; placing it in a game folder supports portable use. Mod authors can contribute or correct metadata. CKAN is open source and MIT-licensed, and is free. On macOS 10.15 and later, the console interface is the default because the graphical interface depends on a 32-bit WinForms application in Mono.

OpenFocus aligns and fuses multi-focus image sequences to create images with focus throughout. It offers ECC and Homography alignment and several fusion methods: Guided Filter, DCT, DTCWT, GFG-FGF and the StackMFF V4 AI model. A wipe view lets users compare source frames with results, and the software can generate depth maps showing focus position per pixel. It supports folder-based batch processing and a headless command-line interface for scripting and CI. Listed inputs include JPG, PNG, BMP, TIFF, MP4 and numbered image folders; the manual also describes decoding additional video formats. Outputs include those image formats, image-sequence folders and GIF animations. Research functions include metadata-calibrated scale bars and multi-page TIFF stacks that preserve 16-bit depth. The interface supports English, Chinese, Japanese and Spanish, with automatic system-language detection. OpenFocus is free under the MIT License, though included algorithms may have separate license terms. Its Windows and macOS app builds are unsigned and may trigger SmartScreen or Gatekeeper warnings on first launch.
